A rare complication of non-displaced or minimally displaced fractures of the distal radius treated with a cast is a delayed rupture of the extensor pollicis longus (EPL) tendon. The EPL is the primary extensor of the interphalangeal joint of the thumb and also assists with metacarpophalangeal extension. Extensor indicis proprius transfer to the EPL is the most widely used and reported treatment for this condition. Magnussen et al. reviewed results of EIP transfer following ruptures of the EPL, with 19/21 good results. None of the cases had any loss of independent index finger extension although index extensor strength reduced to half of that of the contralateral side. Hove et al. reported a similar satisfaction rate following treatment of 15 patients. In his series of 4,400 distal radius fractures treated over a 5 year period, the incidence of delayed tendon rupture following distal radius fracture was 0.3 percent.
